Jingcheng Gongke Gas Tightness Tester 2

Quick Q&A: How does airtightness testing really work? How to define airtightness testing standards

This article introduces the principle of airtightness testing, steps, standard definitions and methods to ensure stable and reliable results. Airtightness testing is through the application of positive or negative pressure to monitor the pressure change to determine the sealing performance, divided into positive pressure method, negative pressure method and other ways, the process includes product positioning, inflation, pressure stabilization, testing and judgment. The development of standards requires comprehensive consideration of various factors. Precision Engineering can provide standardized and customized services for different enterprises, from experimental verification, jig design to mass production line data system integration.
